如何在路由解析中包括查询字符串，以允许具有相同方法，路由和查询字符串的多个操作? [英] How to include Query String in the route resolution in order to allow multiple Actions with the same Method, Route and Query String?

问题描述

我正在将ASP.NET MVC(.NET Framework)应用程序转换为ASP.NET Core MVC.严格来说，这是一次转换，我无法进行任何重大更改，因此无法更改任何路径或方法.我无法匹配ASP.NET Core MVC中的相同功能.

I am converting an ASP.NET MVC (.NET Framework) application to ASP.NET Core MVC. This is strictly a conversion, I cannot make any breaking changes hence I cannot change any Routes or Methods. I am unable to match the same functionality in ASP.NET Core MVC.

有效的ASP.NET MVC:

Working ASP.NET MVC:

  [HttpPut]
  [Route("status")]
  public async Task<IHttpActionResult> UpdateStatusByOrderGuid([FromUri] Guid orderGUID, [FromBody] POST_Status linkStatusModel)
  {

  }

  [HttpPut]
  [Route("status")]
  public async Task<IHttpActionResult> UpdateStatusById([FromUri] Guid id, [FromBody] POST_Status linkStatusModel)
  {

  }

ASP.NET Core MVC无法正常工作.

Not working, ASP.NET Core MVC.

我收到一个错误:

Microsoft.AspNetCore.Routing.Matching.AmbiguousMatchException:该请求匹配了多个端点

Microsoft.AspNetCore.Routing.Matching.AmbiguousMatchException: The request matched multiple endpoints

代码:

    [HttpPut]
    [Route("status")]
    public async Task<IActionResult> UpdateStatusByOrderGuid([FromQuery] Guid orderGUID, [FromBody] POST_Status statusModel)
    {

    }

    [HttpPut]
    [Route("status")]
    public async Task<IActionResult> UpdateStatusById([FromQuery] Guid id, [FromBody] POST_Status statusModel)
    {

    }

在解析哪个路由时，我需要包括查询参数.它应根据查询字符串中是orderGUID还是id进行匹配.

I need to include the query parameters when it resolves which route. It should match based on whether orderGUID or id is in the query string.

谢谢.

推荐答案

为什么不使用单个端点?您不需要传递Guid，因为它是GET操作，因此您可以传递字符串并在以后进行转换.这样，您可以发送一个参数或另一个参数.

Why not use a single endpoint instead? You don't need to pass Guid's, since it's a GET operation, you can pass strings and cast them later. That way you can send one parameter or the other.

[HttpPut]
[Route("status")]
public async Task<IActionResult> UpdateStatus([FromBody] POST_Status statusModel, [FromQuery] string orderGUID = null, [FromQuery] string id = null)
{
    if (!string.IsNullOrEmpty(orderGUID))
    {
        // UpdateStatusByOrderGuid implementation here
        // Guid guid = Guid.Parse(orderGUID);

    }
    else if (!string.IsNullOrEmpty(id))
    {
        // UpdateStatusById implementation here
        // Guid guid = Guid.Parse(id);
    }
    else
    {
        throw new ArgumentException("No valid GUID.");
    }
}

此端点应与您指定的两种方案兼容.

This endpoint should be compatible with both scenarios you specified.
